DSA-110 Event Archive

The DSA-110 is a radio interferometer designed to discover and localize Fast Radio Bursts. The project releases data publicly to support follow-up observations. This page summarizes high-quality, public data sets, including metadata for each event. A low-latency (60 second) alert system is also in development.

Event table

Click on the “PNG file” link to view the candidate summary plot and “DOI” to access the full data release. The search field will filter the table by running a string query on all fields.

Column names:

• Internal Name – Unique internal name generated by the real-time search system. Names begin with an MJD date in format with a suffix that iterates through four lowercase letters (starting at “aaaa”).
• MJD – Modified Julian Date of event (topocentric at top of band).
• DM – Dispersion Measure identified by real-time system in pc/cm3.
• Width – Duration of event (after dedispersion) that produces maximum SNR in real-time search system in milliseconds.
• SNR – Signal-to-noise-ratio of event measured in a single power beam as a function of time (using Heimdall search code)
• RA – Right Ascencion (J2000) of peak of localization probability distribution in degrees.
• Dec – Declination (J2000) of peak of localization probability distribution in degrees.
• PosErr – Error on localization region in degrees.
• Notes – Human annotations describing the purpose of data set or associations, if known. Examples include: test, pulsar, or a name of a known source.
• DOI – Unique, persistent URL to public data set, which includes event localization region and dynamic spectrum. Data and DOI are managed by CaltechDATA.
• PNG file – Summary plot showing event spectrum, localization, metadata.
